It's a misunderstanding because addiction is a habit where the transition cost of adopting the habit is low and the transition cost to exit the habit is high.

This means you can say people voluntarily got into their addiction, but you cannot say they voluntarily stay in their addiction.

Cigarettes are a good example. It is easier to wean off from cigarettes and switch to vaping and then quit vaping, than to quit smoking directly.

This is because the transition cost from smoking to vaping is much lower.
